Behavior differences with VC 8Gb and 4Gb FC
modules
For the VC 8Gb FC module, an interruption occurs when changing the VC fabric type from Static
Login Distribution to Dynamic. This interruption occurs because the module, in reacting to the
change, logs out server HBAs and expects the HBAs to log back in. No interruption occurs for the
similar operation with the VC 4Gb FC module.
VMware—For the VC 8Gb FC module, all virtual machines log in only through the same uplink the
Physical HBA uses to log in. Virtual machine logins cannot be redistributed. For the VC 4Gb FC
module, virtual machine logins can be distributed among all available uplink ports.
The HP VC 8Gb FC module does not provide an embedded SMI-S management interface.
Server login distribution and login redistribution after an uplink port failure on VC 8Gb FC modules
can produce different results than on VC 4Gb FC modules.
